cylinder or even a 6 and will make about 450 fwhp. But with one on each side being pushed by 1.5 liters they will be virtually useless (ie. The spool up characteristics would be awful). In addition the T series is 60s to 70s diesel technology while the GT and especially the GTS series utilizes more effecient wheel and housing combos. I have used a similar set up at one time on an older Z (the T3/T4), and while I can't recite the dimensions, the turbos are SIGNIFICANTLY (sorry about the shouting) bigger than even a GT28 series. Just curious why this choice and what you plan on using it for. Take care, Mark
